iMPROVEMENT IN CARRIAGE-AXLES.

Specification forming part of Letters Patent No. 115,913, datcdJ une 13, 1871.

To all whom yit may concern:

Be it known that l, EENEsT Fnrnnnrcn WAGNER, of Houston, in the county of Harris and State of Texas, have invented a new and useful Improvement in Carriage-Axles; and I do hereby declare that the following is a full, ciear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a new and useful improvement in axles for carriages, wagons, Sie.; and consists in a sleeve, bearing, and linch-pindevice, arranged as hereinafter described.

In the accompanying drawing, Figure l represents a longitudinal section ofthe axle taken on the line :n of Fig. 2. Fig. 2 is a front-end view, and Fig. 3 is a back-end view.

Similar letters of reference indicate corre sponding parts.

A is the axle proper, which is simply a square bar of steel or iron, of suitable size and length, with linch-pin holes in its ends for securingthe wheels. B is a sleeve, which is, by shrinking or otherwise, made fast to the axle so as to form the bearing-arm or journal of the wheel. Gis a collar on the back end of the sleeve. D is a washer at the front end of the sleeve. E is the pipe-box, which is driven into the hub of the wheel. f is a recess in the box for the retention oi' the lubricating material. The interior-of the sleeve B is recessed out for the purpose of lengthening it, as seen at g in the drawing. H is the linch-pin. I is the vhead of the linch-pin; and J is a ring in the head of the linch-pin, which ring passes over the end of the axle and prevents the linch-pin from turning round or rising from the axle.

The advantages are, this axle is cheaper and more easily made than the common axle. It is more cheaply repaired when broken. The piece A is more readily handled in the fire, and can be cut to the required length at once, thus saving the trouble and expense of welding. There are other advantages incident to this mode of constructing axles which must be obvious to all who are acquainted with the subject.

Having thus described my invention, I claim as new and desire to secure by Letters Pat entv 1. The linch-pin H J, washer D, pipe-box E with oil-recess f, sleeve B provided with recess g, and collar C, arranged as shown and described, in connection with the axle-journal A, made square in cross-section, as shown and described.

2. The sleeve B provided with collar C, and the pipe-box E having oil-recess j', arranged in connection with the square axle A, as specified.
